Phoronix: GNOME Shell & Mutter Just Landed More Wayland Improvements

GNOME Shell and Mutter didn't see new 3.17.3 releases for last week's GNOME 3.17.3 development release, but today they've released the new package versions...

Hmm I wonder if I will be able to use my graphics tablet in Krita under Wayland in September? Probably not, but it would be great ...

Yes, I know that tablet support is in Wayland (first-class input device even) and is planned for GNOME 3.18 ...
I'm rather worried that, because Krita (AFAIK) runs under XWayland, there would be complications.
Or is there a working XWayland translation of tablet input? (Sorry, don't have the time to watch the video right now)

I am not sure the details, but I thought libinput also worked under X11?

Yes

It is now upstream.

Unfortunately the thing I'm waiting on have been pushed back (touchpad gestures). Touchpad gestures is a sad story in Linux today.

Sadly true. I remember the multipointer and multitouch demos https://www.youtube.com/watch?v=TBZtSf3sgeQ
I think touch gesture is mostly vendor specific and libinput is mainly a clean up from legacy input drivers.

I have absolutely no clue why they thought it was a good idea to separate mouse, touch and tablet input. It is all esentially the same and having 3 different apis means developers have to work 3 times harder and likely only implement one.

There should just be one "input" event system based off the touch code, which has an enum for the device type. If it is a pen a, a mouse or a finger. That way if you do not care what the user used to click a button it will always still work. But then when you do want to separate pressure or top and bottom of a pen you still can without having to implement a new set wayland proxies and callbacks.

Android does this and it makes much more sense for developers.

First, they really aren't the same at all (on touch, finger down and move is a drag operation; on tablet/touchpad, it's not). Secondly, they really, really aren't the same. Thirdly, Android doesn't actually have the exact same API for them. Fourthly, the touch code would be the wrong place to start. Fifthly, we did that for XI2's multitouch API (where pointer and touch are mostly mashed into one), and it was a disaster, because again, they aren't all the same.
